testdesignen

Testdesignen refers to the process of creating a set of tests, test data, and test procedures intended to validate that a product meets its requirements and quality goals. It translates requirements, user needs, and design information into test objectives and coverage criteria. In software testing, the primary aim is to detect defects efficiently while minimizing cost and effort. The design phase relies on a test basis such as requirements documents, user stories, use cases, and risk assessments, and it results in a suite of test cases and reusable test templates. Requirements traceability is typically established to ensure coverage of functions, interfaces, and quality attributes such as reliability, security, and performance.

Common test design techniques are grouped into black-box and white-box approaches. Black-box methods include equivalence partitioning, boundary value analysis, decision-table testing, state-transition testing, and use-case testing. White-box techniques focus on internal structure, such as statement, branch, and path coverage, and are often used for unit or integration tests. Combinatorial testing methods, such as pairwise testing, aim to reduce the number of test cases while preserving coverage.

The process usually includes selecting design techniques based on risk and scope, drafting test cases with clear inputs, actions, and expected results, defining test data, and ensuring traceability to requirements. Test designs are reviewed, maintained, and updated as the product evolves, and they inform test execution and defect reporting.
